Abstract.

Dumps  are long-term sources of release into the atmosphere of various, including hazardous substances. Therefore, there is an important task of the forecast of air quality near the dumps. Currently, to solve this problem is widely used empirical model of ОНД-86 or analytical models. These models do not allow to take into considerations the wind velocity profile, the geometric shape of blade. This raises an important task to develop effective methods for prediction of air pollution from waste dumps. The paper deals with the numerical model, which allows to solve this problem. The model is based on equations of motion of an ideal fluid and mass transfer equation. For numerical simulation the finite difference schemes are used. The numerical calculation is carried out on a rectangular grid. For the formation of the computational domain and highlight its features markers are used. The results of a computational experiment are presented.
